摘要： A system for intermittently refilling the cartridge reservoir in an ink jet printer from an off-board ink supply tests the ink flow path prior to initiating a refill operation. Air at a pressure greater than the ink feed pressure is applied to the ink flow path to check the integrity of the system. After venting the system to the atmosphere, a slow leak check is made by closing the system, pressurizing it at the feed pressure, turning off the pressure source and, after a short interval, checking the pressure to see if the feed pressure is being maintained. If the integrity check or the slow leak test should fail, the refill operation is aborted and an indicator is set to alert an operator that intervention is required. During the interval the system is being raised from atmospheric to feed pressure, the air displacement is measured and saved as an indication of whether the amount of ink in the off-board supply exceeds a given level. As ink is being transferred into the reservoir, the ink level in the reservoir is monitored. When the ink level does not rise, or rises too slowly, the saved air displacement is used to determine whether to abort the refill operation and indicate a system problem, or set an indicator to signal that the off-board ink supply is exhausted. A controller measures the air displacement by measuring the time, or counting the number of pump strokes, required to raise the system pressure from atmospheric to feed pressure.

摘要： A color ink jet printing device has an off-board ink reservoir for each color being printed. Each reservoir comprises at least two separately replaceable cartridges from which ink is supplied under positive pressure to refill replaceable printhead cartridges. A visual indicator is provided for each off-board cartridge to indicate when the cartridge is empty and this indicator is turned on if the ink supply in the cartridge is exhausted during a refill operation. Printing is not stopped until all off-board cartridges holding one color of ink are empty. At this time the empty cartridges that held any color ink, are replaced. After each operator intervention to replace empty cartridges, the volume of each color ink will be (N−1)/N of maximum reservoir capacity where N is an integer greater than one and represents the number of cartridges in the reservoir. The empty status of a reservoir cartridge is determined by sensing the level of ink in the printhead cartridge a fixed time interval after initiation of a refill operation from the reservoir cartridge.

摘要： An electrophotographic machine has at least two printing modes, with each printing mode having a respective printing density. A method of calibrating the electrophotographic machine includes depositing at least one toner patch on an image-bearing surface. The depositing is performed in a first of the printing modes. Light is emitted onto the at least one toner patch. An amount of light that is reflected off of the at least one toner patch is measured. At least one first electrophotographic condition for the first printing mode is adjusted dependent upon the measuring step. At least one second electrophotographic condition is adjusted for a second of the printing modes. The adjusting of the at least one second electrophotographic condition is dependent upon the measuring step.
